美國(guó)Parker派克溢流閥* 派克溢流閥的工作原理及分派克溢流閥的用途定壓溢流作用:在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中,定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時(shí),會(huì)使流量需求減小。此時(shí)溢流閥開(kāi)啟,使多余流量溢回油箱,保證溢流閥進(jìn)口壓力,即泵出口壓力恒定(閥口常隨壓力波動(dòng)開(kāi)啟)。 Parker派克溢流閥采用外部的電子模塊進(jìn)行控制。借此可以無(wú)級(jí)地選擇溢流功能所需的響應(yīng)的壓力值。針對(duì)各自的壓力等級(jí)在先導(dǎo)閥中裝有相應(yīng)的調(diào)節(jié)噴嘴。直動(dòng)式閥NG06也可以被用作DSA系列的先導(dǎo)閥。當(dāng)壓力超過(guò)調(diào)節(jié)彈簧設(shè)定值時(shí),錐閥開(kāi)啟使P→T或A→B相通。集成式減震閥芯防止過(guò)渡區(qū)里的壓力波動(dòng)。壓力調(diào)節(jié)可以通過(guò)帶有鎖緊螺母的調(diào)節(jié)螺栓進(jìn)行調(diào)定。需要時(shí),也可用圓筒銷(xiāo)子鎖進(jìn)行保護(hù)設(shè)定值。 VBY100K06N1 / Pressure Valves
